Bleedingfrom wound site
Dueto slipped suture, dislodged clot, infection, erosion of blood vessel byforeign body (for example: drain) Maybe internal OR external |

|
Partialor total separation of wound layers Commonlyoccurs before collagen formation (3-11 days)
•Riskfactors – obesity, abdominal wounds |

|
Primary Intention |
Mostsurgical incisions
Woundedges clean, Edges approximated Heal quickly, minimal scarring |
|
|
Secondary Intention |
Largewounds with considerable tissue loss
Example: Burns, pressure sores, severe lacerations. Edgesnot approximated. •Increasedrisks – infection, healing time, scarring. |
